Found a solution.
Issue is the RHI in the Project Settings.
- Open Project Settings.
- Search RHI.
- Go Under Platforms - Windows - Targeted RHIs (presuming you are on that platform).
- Change from Default RHI: Default to DirectX 12.
- Restart the project.
That should solve it.
I always thought that Nanite is supported both on DirectX 11 and 12? At least I remember that being explained in the official docs last year. Newest release and updated docs mention only DirectX 12 and now I do wonder if that is the only one Nanite supports?
Just thinking out loud, would love to hear from someone more experienced so we could all learn!
P.S @Nexusmaster wrote the same answer while I was writing this : )
